Computer Memory- The Brain Of A Computer
In today's digital world, computer is considered to be one of the most essential electronic gadgets of our lives. With the aid of computer, you can easily perform any types of works without any hassle. Moreover, there is an abundance of job positions, which allow people to work from home simply using their personal computer. To work from home, you simply need your computer and an Internet connection. Like human brain, computer can keep all data and files with the aid of computer memory. To store more files and data, a huge storage space is required for a computer.
How can we define computer memory? You already know that the computer in front of you has memory. What you may not know is that most of the electronic items you use everyday have some form of memory also. Computer memory refers to devices that are used to store data or programs on a temporary or permanent basis for use in an electronic digital computer. Computer represents information in binary code, written as sequences of 0s and 1s. Every computer comes with a certain amount of physical memory, usually referred to as main memory or RAM. You can think of main memory as an array of boxes, each of which can hold a single byte of information.
Today, capacitors and transistors, functioning as tiny electrical switches, are used for temporary storage, and either disks or tape with a magnetic coating, or plastic discs with patterns of pits are used for long-term storage. Again, computer memory is usually meant to refer to the semiconductor technology that is used to store information in electronic devices. Current primary computer memory makes use of integrated circuits consisting of silicon-based transistors. There are two major types of memory namely volatile and non-volatile.
Volatile memory is a kind of computer memory that requires power to maintain the stored information. Current semiconductor volatile memory technology is usually either static RAM (see SRAM) or dynamic RAM (see DRAM).
On other hand, Non-volatile memory is computer memory that can maintain the stored information even when not powered. Examples of non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, pen drive etc.
